Nah, you are just being overly negative because Tomlin isn't a good coach.
There is way too much talent for the Steelers to not win at least ten games. Come playoff time, I have zero faith Tomlin won't don what Tomlin does.
Hopefully they don't re-up Bell, because that's a contract they will regret sooner rather than later. I also firmly believe they have to change the culture in that room, and he's a big part of the issue.
You simply don't need dominant RBs in the modern NFL. I can't even remember the last team with a great RB to win the SB, maybe Lynch, and that's really it in the last dozen years or more.
